Colt 1911 7.62 x 25 Conversion Kit

[rem22long40x]

Gun parts has a new kit for 9mm.&38super 1911's . the 7.62x25 Is a fast /hot little round and I think it will be a neat project . after I complete my treatment for my most recent brain tumor I will install one of these kits ,if any one has already done one let us know how it dose .I will be away fore at least one and a half months , so gods speed and keep your powder dry thanks David

Works fine in my 9mm, use 38 super mags and mag loader, I can get 8 in the mag with modifction to the round.

Seeing as how the 7.65x25 is 1/10" inch longer then a .45 ACP or .38 Super?

How do they propose you get the cartridges to fit in the magazine?

There is also some misinformation in their item description too.

which is necessary to cycle the lower pressure 7.62 x 25 ammunition.

This is not true.
.45 ACP is rated at 21,000 PSI.
7.62x25 pressure runs all over the map on surplus ammo, but is considered to be about 40,000 PSI, or well over the .38 Super at 36,500 PSI.

The barrel is unmarked and includes a flat crown, which allows the Tokarev ammunition to shoot flatter.

Pure and total BS!

The way a barrel is crowned has nothing at all to do with how "flat" a cartridge shoots.
Sounds to me like they just went the cheapest route possible and faced it off in a lathe.

the flat crown WILL effect the accuracy , you just need to be more careful not to damage the crown . for instance my 40x Rem 22 long rifle match rifle has a flat crown and is one of the most accurate gun I own . that said the crown has a lot to do with accuracy for any fire arm. thanks David

I should read what I write before sending. I meant to say "with out" modding the cartridge, I used a mag loader and the bullets sit at an angle and do feed OK.

That puzzles me, also. I can't get Russian 7.62x25 in either a .38 Super or a .45 magazine. Maybe playing with the feed lips and follower so the rounds seat at an angle would work, but I haven't tried that. How did you get it to work?

As to pressures, there are those mystical 7.62x25 rounds that have a velocity of 5000 fps, a pressure of 100,000 psi and will blow up every pistol in the world except a Vz-52. Then thare are the real 7.62x25 loads that run about the same as the .38 Super and the standard 9mm Parabellum European loads or about 36,000, which is about what the Russian rounds run. I would not be concerned about pressures in a Model 1911, especially since a 7.62x25 barrel would be a lot thicker than the normal .45 ACP barrel.

That sounds interesting. And I wish you the best in your treatments. You will be in my prayers tonite.

 

[Jim Watson]

I read all I could find on the modern conversion.
Apparently you can load from 4 to 8 rounds depending on the peculiarities of ammo and magazine.
One experimenter was deep seating and recrimping Iron Curtain surplus to get a full load in the magazine. He said it shot but the fired primers were really ugly if you attach importance to that "pressure sign."

also agreed. the crown is very important for accuracy but has nothing to do with trajectory and ballistics of the round. i guess i can see how if the top of the crown was messed up that it would worsen the trajectory but thats about it

How to load the mag

[Jim Watson]

Wish he had actually shot the gun loaded that way.
Or at least hand cycled the rounds through.
Wonder if it started out as a .45 like he said. (Doubtful)
Wonder if he used .38 Special magazine like the caption. (Not)

 

[ApacheCoTodd]

That's informative (the video) but I can't wrap my head around needing a tool to load a pistol mag. Is that tool necessary or just highly recomended?

I'd kinda like to try a conversion for my AMT long slide in addition to 10mm - can't help but think I'll need a lot more spring (recoil) than is currently in there.

 

[Jim K]

I have seen an M1911A1 converted to 7.62x25 by the Viet Cong. They filed a lot off the inside front and back of the magazine well and made a new magazine out of sheet metal. They also worked over the extractor slot and extractor and built up the other side of the breech face with brazing. It fired OK, but I am assuming here that the "conversion" would not involve that much alteration of the gun.

The VC only had access to .45 1911s. For the 7.62x25mm conversion advertised you start with a .38 Super 1911, a lot simpler conversion.

My question is.... Why?

 

[Jim Watson]

Why?
Because it's there.

I have read many posts by people who learned to like the .30 Commie Pistol round in Tokarevs and CZs but wanted a "modern" gun in the caliber. Maybe because the ammo was cheap and it gave a loud bang and bright flash. I know one guy for sure who likes the fireworks and handloads to get more.

Unfortunately this seems to be the usual case of a day late and a dollar short.
There is not the wide availability of cheap Iron Curtain Surplus ammunition that helped sell those TTs and CZs. Note that the video shows loading fresh commercial S&B 7.62. He's getting the ballistics but not the economy. Just as well shoot 9mm.
